A new sex study, carried out by married and attached dating website Victoria Milan found that most people insist that oral sex is a must when having an affair.

The study also found that a lack of oral sex in a relationship can sway a person towards cheating.

According to metero.co.uk , 9,107 users on the Victoria Milan site were surveyed and 65 per cent of women and 68 per cent of men said that they would not be interested in having an affair with somebody who was not interested in oral sex.

Most likely due to the general perception that sex in general is more intimate for women, the survey found that straight women in particular do not perform/receive oral sex as much as others.

The Victoria Milan survey also found that an interest in oral differs from country to county. For example, 82 per cent of women and 79 per cent of men in the UK say that they enjoy giving oral, while in comparison, a lesser 71 per cent of women and 68 per cent of men in New Zealand said that they enjoy it.
